A very long two day/1 night trip that we did on my 31st birthday! We were trying to finish the Possum Creek Gorge on day two, but it proved to be too difficult for us that particular day so we turned around at the Little Possum Creek Campsite and walked 3.2 miles back to the Heiss Mtn Trailhead. We would have camped there and finished the next day, but unfortunately my wife didn't have Memorial Day off from work this year.
